The correct answer is Option B.
OBSTREPEROUS means noisy and difficult to control.
Thus NOISY is the synonym of the word because both the words mean the same.
The remaining options are incorrect because they mean differently:
CHEERFUL means happy and optimistic.
CALM means peaceful and tranquil.
OBSTINATE means stubborn and headstrong.
